Timezone Converter: Convert Time Between Timezones | Free Tool

A Yes, our Free Timezone Converter includes a convenient 'Swap Timezones' button, usually located between the source and target timezone selectors. Clicking this button instantly reverses your conversion, making the original source timezone the new target and vice-versa. This feature is perfect for quickly comparing times from both perspectives without re-entering any data, saving you time and effort for international scheduling.

A The converter handles past dates perfectly fine. If you're looking to schedule a meeting that happened last week, just input the original date and time. The tool will accurately display the corresponding time in your target timezone, accounting for any DST shifts that may have occurred since then. This is handy for historical research or reconciling past events.

A Absolutely. Enter the date and time for your first meeting, and the converter shows the target timezone equivalent. For recurring meetings, note that DST changes might shift the time by an hour in spring or fall. The tool handles those transitions accurately per date. A practical tip: check the conversion again a few days before each DST change to confirm your meeting time still works.

A You might be looking at a city that uses a unique offset, like Nepal which is UTC+5:45, or India at UTC+5:30. The tool pulls real IANA timezone data directly from your browser's database, which covers half-hour and even quarter-hour offsets. If you're used to thinking in full-hour zones, these can look wrong at first glance. They're correct. Always double-check the specific city name, not just the country, since some countries like Australia span multiple zones.

A It runs entirely in your browser, but you need internet to load the page initially. Once loaded, the timezone data stays cached in memory for the session. The conversion itself happens client-side, not on a server. If your internet drops while using it, the tool keeps working until you refresh the page. That's handy on shaky hotel Wi-Fi or during flights with spotty coverage.

A Yes, absolutely. Two cities might share the same standard offset but switch DST on different dates. For example, New York and Santiago both use UTC-5 in winter, but Chile shifts in September while the US shifts in March. Our tool handles this because it uses the IANA timezone database, which tracks each region's specific rules. Just pick the exact city or region name, not just the offset. Double-check your results around the spring and fall transition weeks.

A Pick a major city in the same timezone instead. For instance, if you need Porto and it's not listed, choose Lisbon — they're both in Western European Time. The dropdown covers 45+ zones but skips smaller towns. Another option: use the UTC offset closest to your target. London matches UTC+0, Berlin fits UTC+1. Still unsure? Check the country's official IANA timezone name and match it manually.

A Yes, it does. The IANA timezone database tracks each region's DST rules separately. Melbourne shifts in October, London shifts in March. Those two are months apart. When you convert between them around those weeks, the tool automatically adjusts. I've seen people trip up assuming DST is universal. It's not. A practical example: converting from New York to Sydney in late March will show a 16-hour difference, not 14. That's because Sydney already switched back while New York hasn't yet. Always check the specific date, not just the time.

A Yes, but only if you pick the exact city or region name, not just the UTC offset. The tool pulls DST rules straight from the IANA database, so converting New York to Berlin in late March will show 6 hours difference, not the usual 5. That's because the US switches earlier than Europe. If you pick a generic offset instead of a city, you'll get a wrong result around transition weeks. My tip: always select a named location and double check meetings scheduled near DST shifts.

A Countries like the US, Canada, and Brazil span multiple timezones. Converting New York to Los Angeles is 3 hours, but New York to Chicago is only 1. The tool uses the IANA database, so it reads each city's exact zone. If you pick a generic country option, it defaults to the capital. That's why New York to Dallas might show 2 hours. Always type the city name, not the country. For example, São Paulo and Manaus are an hour apart, so check the dropdown before trusting the result.
